CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 533,892, dated February 12, 1895.

I Application filed July 9, 1894. Serial No. 5161957. We model.)

To ctZZ whom it may concern:

Be it known that I, EUGENE K, HELLER, a citizen of the United States, and a resident of Sauk City, in the county of Sank, and in the State of Wisconsin, have invented certain new and useful Improvements in Cash-Registers; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its object to provide a simple, economical and accurate cash register; the same consisting in certain peculiarities of construction and combination of parts hereinafter set forth with reference to the accompanyingdrawings and subsequently claimed.

In the drawings: Figure 1 represents a vertical longitudinal section of my improved cash-register, the section being taken on line 1-1 of Fig. 3 5 Fig 2, a horizontal section of v the register viewed on line 2-2 of the preceding and succeeding figures; Fig 3, a vertical transvere section of said register; Fig. 4, a detail sectional View illustrating a portion of an adding disk, a pivotal dog carried by the same and a cam in the path of the dog; Fig. 5, a similar view illustrating the aforesaid dog in clutch with a pair of adding disks; Fig. 6, a detail elevation partly in section illustrating a lever-and-stop mechanism embodied in my invention, and Fig. 7, a detail elevation of the portion of the aforesaid register at which the amount of a purchase is indicated by the salesman.

Referring by letter to the drawings, A represents a casing of any suitable design and dimensions provided with apertures 17 through which the amount of a purchase may be indicated, these apertures being either front or rear as may be found most convenient or desirable and preferably glazed. The casing may be supported over a cash-drawer B as shown in Fig. 3, and in this event the drawer will be provided with a spring-catch c or other suitable means forming part of a mechanism for releasing gravity pawls or latches hereinafter specified.

The interior of the casing A is accessible through an opening that is closed by a door 0 and this door is normally locked. Rising from the bottom of the casing are a series of stems D, and loose on each stem is a ratchetdisk E that in every instance has a dog F pivotally connected to its hub. Arranged on the bottom of the casing is a lifting cam G in the path of each of the aforesaid dogs, and springdetent H are supported on said casing-bottom to automatically engage the notches of the ratchet-disks E, these notches being radial and of such number as may be suited to fractional divisions of any currency, said disks herein shown being schemed to denote cents, dimes and dollars, or in other Words each of the aforesaid disks is provided with ten notches indicated by characters of the Arabic notation. By means of its relative detent each disk is locked against movement, except in one direction, the inner ends of said detent and the disk-notches being suitably beveled to permit a ready disengagement of one from 'the other when rotary motion is imparted to said disk by the means hereinafter specified.

A vertical stem I turns loose in the casingbottom and a plate J parallel thereto. Fast on the latter stem is another disk K provided with radial notches that are engageable with a spring-detent L and indicated by characters of the Arabic notation, this latter disk being for the registration of amounts in excess of what can be registered by the preceding disk, and according to the scheme of the present register, said latter disk is for the registra tion of dollars in amounts of ten. The disk E, their cam-actuated dogs and spring detents may be indefinitely multiplied, and succeeded by the disk K or the latter may be omitted.

Loose on the stems D above the disks E are hubs cl of cylindrical shells M having their upper edges provided with notches corresponding in number to those in said disks, and these notched edges of the shells are engaged by gravity latches N hung from arms e of the plate J above specified. The periphery of each shell is provided with characters similar to those on the adjacent disk, and these characters come in View through the apertures in the casing.

An arm 1 radiates from the hub of each cylindrical shell, and carried by this arm is a gravity-pawl O that engages with the adjacent disk to cause rotation of the latter in the proper direction.

Each shell and disk that operates in conjunction therewith rotate in a direction 0pposite that of the adjacent similar devices, and it will be apparent that any amount indicated by rotation of either shell will be registered by the corresponding disk. It is also to be noted that in progressive order of the series each disk adds on to the other, or in other words the dog F pertaining to one disk is lifted by its relative cam G to come in clutch with a notch of the succeeding disk as the former disk is about to complete one revolution, and consequently said succeeding disk is automatically moved one degree of its total revolution to register a full turn of its predecessor, after which said dog drops to its normal position.

A red P loose in suitable bearings is provided with lateral pins g that come under the gravity latches N, and a weighted arm 72. depending from the rod is herein shown as be ing in the path of a lever Q that is actuated by the spring-catch c or other suitable device on the cash-drawer when the latter is drawn out, the result of this operation being a lift of the gravity-latches to free the indicating shells and thereby permit of the latter being returned to normal position by any suitable automatic mechanism, said normal position of the shells being such that the cipher on each will appear through the adj acent aperture in the casing. The weighted arm automatically returns the rod to its normal position and thus permits the gravity latches to come again in engagement with the ratchet-edges of the indicating shells, but while I have described said rod actuated by mechanism in connection with a cash-drawer it may be extended through the casing ad rocked by hand to lift 'said pawls.

The hubs cl of the cylindrical indicating shells turn in the plate J above specified and are provided with pinions R that mesh with weighted segmental racks S at the inner ends of levers T that work in slots in the casing.

By means of the levers and rack-gear, the cylindrical shells are operated to indicate the amount of a purchase through the apertures in the casing and when the gravity latches N are lifted out of engagement with said shells the weighted racks operate to cause the automatic return of any depressed levers and corresponding shells to normal position, these shells being provided with lugs i that come against stopsj projecting from the plate J set forth in the foregoing.

Adjacent to the casing slot for each lever T, I provide a series of push-keys U that are resisted by springs 7c,tho latterserving to antomatically return said keys to normal position afterbeing depressed. Each key is provided with a notch normally in the path of the lug m on the adjacent lever, whereby said lug may clear all of the keys preceding the one depressed. As a matter of conveniencethe keys in each series are preferably numbered from 1 upward in successive order as shown in Fig. 6, and from the foregoingit will be understood that when any one of said keys is pushed in and held, it will act as a stop to prevent the relative lever from being pulled farther than necessary to bring the desired character on the corresponding shell in register with the observation aperture in the casing.

From the foregoing it will be seen that the amountof a sale may be readily indicated and registered, while at the same time said amount is automatically added to previous sales and the total amount at any time may be readily determined when the casing is opened to bring the adding disks to view.

The adding disks may be readily adjusted to have them all start from 0, this operation being accomplished by turning said disks in successive order from the lowest to the highest denominations when the spring-detents and gravity-pawls are held out of working position.

Inasmuch as some variation may be made in the structural detail of the cash-register herein shown and described without effecting a change of lresults, I do not wish to be understood as limiting myself to any specific means for rotating each indicating shell and effecting a simultaneous rotation of the relative adding disk, nor to the specific means for effecting an independent automatic return of the shells to normal position; neither do I wish to he understood as limiting myself to specific devices for locking the adding disks against reverse movement, nor to any particular means for communicating motion from one of said disks to the next in the series.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
